Electri Terminal Calculator

# Electri Terminal Calculator - User Guide ## Overview Electri Terminal Calculator is a Chrome extension for quick terminal selection reference. It helps engineers, buyers, sales support teams, and electrical component users convert and check common terminal-related dimensions directly in the browser. The extension includes: - AWG to mm2 reference lookup - mm2 to AWG and color-code matching - Maximum current reference from the bundled selection table - Stud size and terminal hole-size lookup - Terminal type code lookup - Insulation code lookup - Right-click selected text parsing - One-click copy for engineering reference notes This tool is designed as a fast engineering reference. It does not replace the final product specification sheet, customer application requirements, certification requirements, or engineering approval process. ## Who This Extension Is For Electri Terminal Calculator is useful for: - Electrical engineers checking wire and terminal compatibility - Wire harness engineers matching cable sizes and terminal holes - Purchasing teams reviewing customer requirements - Sales engineers preparing quick replies for RFQs - Industrial component users comparing AWG, mm2, stud size, and hole size values - International customers who need to switch between US and metric notation ## Main Features ### 1. Wire Size Calculator Use the Wire tab to look up AWG and mm2 reference values. Supported examples: - `AWG 10` - `10 AWG` - `8 mm2` - `1/0` - `2.63 mm2` The result may include: - AWG value - Wire size range in mm2 - Terminal color code - Maximum current reference - Notes about the matched range Example: Input: `AWG 10` Result: - AWG: 10 - Wire range: 2.63-6.64 mm2 - Color code: Yellow - Max current: 48 A ### 2. Stud and Hole Size Calculator Use the Stud tab to match stud size and terminal hole size. Supported examples: - `#10` - `M6` - `6 mm` - `1/4"` - `10.5 mm hole` The result may include: - Stud size in inch notation - Stud size in mm - Recommended terminal hole size in mm - Terminal hole size in inch notation Example: Input: `M6` Result: - Stud size: 1/4" - Stud metric: 6.0 mm - Hole metric: 6.4 mm - Hole inch: .252 inch Important note: Stud size means the fastener diameter. Hole size means the terminal tongue opening. Always confirm the final hole size against the product drawing and assembly tolerance. ### 3. Terminal Type Lookup Use the Type tab to search terminal family names or model codes. Supported examples: - `ring` - `spade` - `FD` - `butt` The result may include: - Terminal type - Code - Insulation code reference - Wire size reference - Size reference - Tongue width reference Example: Input: `ring` Result: - Ring Terminals - Code: R - Insulation reference: NYD - Wire reference: 1.25 - Tongue reference: 3.7 ### 4. Insulation Code Lookup Use the Insulation tab to search insulation code, material, or crimp structure. Supported examples: - `NY` - `NYD` - `D` - `vinyl` - `nylon` The result may include: - Insulation code - Crimp type - Material - Temperature rating - Usage note Example: Input: `NY` Result: - Code: NY - Crimp type: Nylon Insulated - Single Crimp - Material: Nylon - Temperature rating: 105 C ### 5. Right-Click Text Parsing You can select terminal-related text on a webpage and send it to the extension. How to use: 1. Highlight text on any webpage. 2. Right-click the selected text. 3. Choose `Calculate with Electri Terminal`. 4. The extension will parse recognized wire, stud, terminal, or insulation values. Example selected text: `M6 ring terminal for 10 AWG cable` Possible results: - AWG 10 wire reference - M6 / 1/4" stud reference - Ring terminal type reference The extension only processes text that you actively select. ### 6. One-Click Copy Each result card includes a Copy button. Use it to copy a clean engineering reference sentence for emails, RFQs, BOM notes, or internal comments. Example copied text: `Reference selection: AWG 10, 2.63-6.64 mm2, Yellow color code, max current 48 A. Confirm terminal form, insulation code, and product specification before final selection.` ## How To Install From The Chrome Web Store After the extension is published on the Chrome Web Store: 1. Open the Electri Terminal Calculator listing in the Chrome Web Store. 2. Click `Add to Chrome`. 3. Review the permission prompt. 4. Click `Add extension`. 5. After installation, click the puzzle icon in the Chrome toolbar. 6. Find `Electri Terminal Calculator`. 7. Click the pin icon if you want the extension to stay visible in the toolbar. 8. Click the extension icon to open the calculator. ## How To Install For Local Testing Use these steps only if you are testing the unpacked extension before Chrome Web Store publication. 1. Open Chrome. 2. Go to `chrome://extensions`. 3. Turn on `Developer mode`. 4. Click `Load unpacked`. 5. Select the extension folder. 6. Confirm that `Electri Terminal Calculator` appears in the extension list. 7. Click the extension icon to open the popup. If you change extension files during testing, return to `chrome://extensions` and click the reload button for the extension. ## How To Use The Extension ### Step 1: Open The Extension Click the Electri Terminal Calculator icon in the Chrome toolbar. The popup opens with four tabs: - Wire - Stud - Type - Insulation ### Step 2: Choose A Mode Choose the tab that matches your task: - Use Wire for AWG, mm2, color code, and current reference. - Use Stud for screw, bolt, stud, and hole size reference. - Use Type for terminal family and code lookup. - Use Insulation for insulation material and crimp structure lookup. ### Step 3: Enter A Value Type a value into the input field. You can also click one of the example chips shown under the input. Examples: - `AWG 10` - `8 mm2` - `#10` - `M6` - `ring` - `NYD` ### Step 4: Review The Result The extension will show one or more matching reference cards. If more than one result appears, review each…
